I'm getting the following codes and messeages:
P1400, P0174, P0302, P0304, P305, P306, P0316, Inc Catlyst, Evap., O2 Snsr, O2 HTR, Ready Misfire, Fuel, Comp., EGR.
It idles rough. Smell gas when started. Original the only code was EGR bad. Changed EGR still not fixed. Then I changed the plugs abd wires and then that is when the other problems started.
